The gradient vector field of function f(x,y) is given as follows:
grad(f(x,y)) = (1 + 3xy)e^(3xy) i + 3x²e^(3xy) j.
How to obtain the gradient vector field of a function?
Suppose that we have a function defined as follows:
f(x,y).
The gradient function is defined considering the partial derivatives of function f(x,y), as follows:
grad(f(x,y)) = fx(x,y) i + fy(x,y) j.
In which:
- fx(x,y) is the partial derivative of f relative to variable x.
- fy(x,y) is the partial derivative of f relative to variable y.
The function in this problem is defined as follows:
f(x,y) = xe^(3xy).
Applying the product rule, the partial derivative relative to x is given as follows:
fx(x,y) = e^(3xy) + 3xye^(3xy) = (1 + 3xy)e^(3xy).
Applying the chain rule, the partial derivative relative to y is given as follows:
fy(x,y) = 3x²e^(3xy).
Hence the gradient vector field of the function is defined as follows:
grad(f(x,y)) = (1 + 3xy)e^(3xy) i + 3x²e^(3xy) j.
